Obviously i didnt make this but i thought it could be used for a custom story. Just find something to convert it with, if you cant il do it but just ask ok?http://www.youtube.com/watch?v=uzOb3UhPmig
btw if you can listen to the whole thing for 10 mins in a dark room, you are very very brave

Harrowing, yes, but in practice it's simply too changing (and long) to be even credits music. You could use parts of it for short effects, but the high strings will be sort of distracting.
It's probably worth listening to some other music by Penderecki. I see that there's a playlist.
